Tokyo: Asian shares climbed to a two-week high on Monday, and the Australian dollar and copper gained, as China said its manufacturing expanded in August at the fastest pace in more than a year.
A delay in potential US military action against Syria, as US President Barack Obama sought Congressional support, also helped boost short-term risk appetite.

China's official purchasing managers' index (PMI) rose to the highest level since last April and topped market expectations.
"This will reinforce views of China stabilisation. It is a risk positive, if only because it removes some of the short-term risk that the China slowdown could spiral further downwards," Citi's Englander wrote in a note.
A separate manufacturing PMI report from HSBC, released on Monday, showed activity in privately-owned factories increased over August for the first time in four months.
The yen had risen recently on heightened geopolitical tensions and as investors dumped emerging market currencies to position themselves for the U.S. Federal Reserve to begin reducing stimulus, perhaps from its meeting later this month.

Brent crude prices dropped 1 percent to below USD 113 a barrel, on track for a third-day of decline. They touched a six-month peak of USD 117.34 last week on concerns that a U.S. military intervention could lead to retaliation and disrupt crude supply in the Middle East region, which pumps a third of the world's oil.
Safe-haven gold shed 0.4 percent to around USD 1,390 an ounce, hitting a one-week low.
